IMPROVEMENT IN APPARATUS FOR COOLING AIR AND REFRIGERATING BUILDINGS.

Specification forming part of Letters Patent No. 1117,2S, dated February 10, 1874; application filed June 7, 1873.

To all whom it may concern:

Be it known that I, Josnrn Phnrsnrrn, of Indianapolis, in the county of Marion and State of Indiana, have invented certain Improvements in Refrigerators, of which the following is a specication:

This invention relates to that class of refrigerators in which the air of the refrigerating or cooling chambers is made to circulate continuously through an ice-chest situated either in or in proximity thereto; and it consists in the arrangement, hereinafter more fully described, ofa series ofair-pipes in connection with an air-pump or fairblower, by which the above object is accomplished in a more thorough 1n anner, and the temperature of the cooling-chain ber reduced to a-ny desired degree with a less quantity of ice, than is required by any of the I I refrigerators of a similar nature now in use.

Figure l is a vertical longitlnlinal section of a refrigerating-chamber having an icc-chest and air-circula-tin g pipes embodying my invention arranged therein. Fi 2 is a horizontal section of the same. The refrigerating-chamber A may be a box or close room of any desired size to contain articlcs to be cooled, from a few dishes of cream to any number of the carcasses of cattle or hogs. B is the ice-box, in which ice, either by itself or combined with salt or other known refrigeratin g substances, is deposited. Itshonld be made water-tight, so as to retain the brine of the melted ice and salt, as this will serve to reduce the temperature of the air to the lowest practicable degree, as Well as to take up impurities from it as it is circulated through the water and ice. Any excess of brine may be drawn off by means of a stop-cock at the bottom of the ice-boX. This ice-chamber may be placed in any desired position in the room designed to be cooled; but I prefer to place it at or near the ceiling and in the center of the room. The air is circulated through the icebox, and the chamber to be cooled by the following-described arrangement of pipes and air-pump or fan-blower, the latterA being operated by'any convenient or suitable means. O is the air-pump or fan-blower, which may be of any desired construction and situated in any convenient position in the room, or, if desired, in an adjoining room. With pump O are connected imlucticlrpipe D and eduction-pipes E F. The eduction-pipes F pass through the upper part of the ice-chest, and from these pipes G extend down to within a few inches of the bottom of the chest, andterminate in a horizontal pipe, H, the ends of which are bent to one side in opposite directions, as shown in Fig. 2, so as to give the air a rotary circulating motion through the ice and Water contained inthe ice-box B, and which serves the double purpose of agitating the ice and water, thereby reducing the temperature, and also of purifying the air as it circulates upward through it. The air is returned downward through the large vertical pipes I, from which it is discharged into the chamber A, cooled to as low a temperature as its passage through the ice and water, and the pipes surrounded by them, will reduce it. rlhc pipes G are attached to the pipes F, and also the pipes H to the pipes G, by means of what are `known as 'T- couplin gs,77 in such a manner as to be detach able, for the purpose ofremoving them at such times as it becomes necessary to clean out the ice-box, which generally occurs once in about three months.` The eduetion-pipe E passes horizontally through the ice-chamber B near the bottom, as shown, and discharges the air directly into the refrigerator and chamber A, the object of which is to both cool and agitate the air therein. rlhe induction-pipe D is `arranged to return the warmer air from the upper part of the refrigerating-chamber to the pump, by which it is forced back through the eduetionpipes E and F into the ice-chamber B. By thisnieans the air of chamber A is constantly circulated throughout the room and through the ice-box B, thereby reducing the temperature of the chamber A and cooling the articles placed therein.

It desired, the ice-chest B may be located above the refrigerating-chamber A.

I claim as my invention- The arrangement of the air-circulating pipes E, F, G, H, and I within an ice box or chamber, B, situated in or in proximityto a refrigerating-chamber, A, in combination with the return or induction pipe D and air-pump O, arranged substantially as and for the purpose set forth.
